7 Claims. 1

This invention relates to new and useful improvements in a combined carrier and stand for motion picture projectors.

The present application is a substitute for my abandoned application filed on June 25, 1942, Serial No. 448,404.

More specifically the invention proposes the construction of a combined carrier and stand for motion picture projectors characterized by a rectangularly shaped tubular housing having its .front and back sides open and arranged in a manner so as to receive and house a motion picture projector and films for use therein.

Still further it proposes to provide covers hingedly mounted upon the bottom portion of the housing for extension across the open sides of said housing for closing the same and arranged in a manner to be extended downwards at an outwardly diverging angle for forming legs for supporting the tubular housing at an elevation 1.

to permit the same to be used as a stand for supporting the projector at an operative elevation.

A further object of this invention proposes the use of angularly shaped brackets arranged in a novel manner between the end walls of the tubular housing vand portions of the covers in a manner to retain the covers in the. downwardly and outwardly diverged pivoted positions.

A further object of this invention proposes to mount lugs removable upon the top wall of the housing in a manner to permit a carrying handle to be engaged therewith in the closed condition of the carrier to be conventionally carried from place to place.

A still further object of this invention proposes the application of extendable leaves to the top wall of the housing whichare adapted to be pivoted to a horizontal position when the covers are pivoted to their downward position for the purpose of increasing the overall width of the top wall to provide a greater amount of space to increase the supportin area of this top wall.

' For further comprehension of the invention,

of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended ,claims in which the various novel features of the invention are more particularly set forth- In the accompanying drawings forming a mate rial part or" this disclosure:

The combined carrier and stand for a motion picture projector according to this invention comprises a rectangularly shaped tubular housing I 9 having its front and back sides open and adapted to receive and house a motion picture projector ii and films ii. The housing more specifically consists of a top wall i3 and a bottom wall M which are held in a superimposed spaced condition by means of a pair of spaced vertical parallel extending side walls [5.

The motion picture projector normally rests upon the bottom wall I 4 and a means is provided for conveniently carrying the films 12 in a rolled condition upon conventional film spools. This means comprises a shelf it having one end attached to one of the end walls 55. The other end of the shelf [6 is attached to a downwardly extending bracket 11. This bracket I! has its L-shaped grooved channels 28.

shown in Fig 2.

A means is provided for closing the open front and back sides of the housing; H]. -This.--means comprises a pair 'of covers 20 mounted upon the bottom portion of the housing and extending upwards across the open front and back sides of the housing.

and back edge portions of the bottom wall Hi of the housing it and are provided with locks 20 which may close or release the cover'2fi by using a key through the key hole 29 These covers in the inoperative position of thecarrier are extended across the open sides ofthe housing. However, it is possible to pivot the covers 20 into'a downwardly and outwardly diverged position for acting as legs for supporting the housing at an elevation to support the projector ll upon the top wall of the housing 53 at an elevation at which it might be used to project a film upon a screen.

The free edge portions of the cover 29 are provided with rubber elements 22 which are adapted to engage against the floor or other supporting surface when the covers 20 are being used as legs for frictionally holding the stand in position and prevent accidental -movement thereof.

Means is also provided for holding the covers 29 in their outwardlyand-downwardlydiverged positions. This means comprises a pair of inverted L-shaped brackets 23 for each of the covers 29. These brackets 23 comprise a vertical long "arm Edeand a short top arm 23 extending at right angles tothe vertical portion =-23"-. The

bottom 'ends of the vertical portions 23 are These rollers 25 are spaced from the adjacent face of their respective brackets' 2-3 by'means of a spacer blockZ'i mounted uponthe pints and arranged between the adjacent faces of thebracket 23 and theroller 25. The short arms 23' are also formed with hooks 25 adapted to be frictionally engaged by springcatches 2i, secured to the bottom side of the shelf l6, and to hold the brackets 23 by the tension of the spring catches 2i when the cover is closed.

The inside face ofthe spaced end walls iiiof the housing I0 are provided With substantially I V The groovesin these channels 23 are T-shaped in cross section for housing the rollers 25. Each of the grooved channelsfld comprises a vertical portion fideand a bottom portion ZS eXtended upwards and out- 7 ,wards from the bottom end of the vertical portion 23 The construction is such that when the covers 28 are in their closedposition the rollers .25 are housed within the top end of the vertical portion 28 of the gro oved channel 23 as To open the covers 2% it is .merely necessary to pivot the same about the hinges 2i -which will cause the brackets 23 to move therein and move ther0llers 25 to an These covers;- 29. arepivotally supported by means of hinges 2| upgnthe front aligned position with the bottom portions 28 of the grooved channel 28.

The top ends of the brackets 23 are then pulled outwardly to cause the roller 25 to move along the length of the upwardly diverged end portions 28 of the grooved channel 28. Due to the fact that these bottom end portions of the grooved channel-"28 are divergedupwardly the rollers 25 will retain their engaged position within the end of these portions 28 of the groove until the -brackets- 23; are again manually urged inwardly to cause the rollers 25 to be aligned with the vertical portions 25 of the grooves.

Lugs are removably mounted on the top wall of the housing lfifor receiving a carrying handle 23in the closed position of the carrier as shown in'Fig. lto permit the device to be conveniently carried from place to place. Each of these lugs comprises an inverted U-shaped bracket 38 having the bottom ends of its side arms securely attached to an enlarged metallic plate 3!. The inverted U-shaped brackets 39 are adapted torbe extended upwards throughspaced openings 32 formed in the top wall it of the housing Ill. -The openings 32-are slightly smaller than the plates 3i so that the plates will engage the bottom face of the top wall 53 and prevent the u shaped brackets 33 from being completely pulled through the openings 32.

The carrying handle 23 is of a type to include handle portion 29 providedat itsends with spring clips 2255 engageable upon the intermedi ate arm of the U-shaped bracket llfl. :When the .clips 2 engage the U-shaped brackets 33, the

handle portion 29" may bev manually gripped for carrying the housing. about. Howevenavhen the carrier is being used as a stand thespringclips .29 are disengaged from the brackets '36 permitting the brackets to be withdrawn. as shown in "Fig; 11, thus providing an unobstr-ucted'top wall [3 upon which the projector l i may be positioned as shown in Fig. 6.

Extendable leaves 33 are-mounted upon the sides-of the top wall l3. These leaves are pivotally mounted upon the sides of the top wall l3 by means of hinges 36. These leaves are adapted to be pivoted to a horizontal position to be extended laterally from theside of the top wall i3 as shown inFigs. Gand '7 to'increase the overall top surface of this top .wall.

Means is provided for holding the leaves 33 in their laterally extended-positions from the sides of the top wall i3. This means comprises a bracket for each end of each of the leaves 33. Each of these brackets comprises a pair of sections-35 having their adjacent ends pivotally-attached together with the free endof one section attached to a lug 36 -mounted upon the bottom face of the leaf 33.

The free end of the other section ispivotally attached to the inside face of its respective end wall I5 by means of a pin 31. The construction of the brackets for supporting the leaves 33 is such that when the leaves 33 are pivoted to the operative positions the sections of the brackets shape a dead center to retain the shelves in their operative positions until such time as the sections of the brackets are manually urged to again pass their dead center. i Y

The operation of this invention is as follows:

The carrier is carried-fromplace to placejn the condition shown in Fig. 1. When the destination is reached where it is desired .to show a extended positions by lifting the same upwards causln 'the sections of the brackets to pass the-dead center and maintain these leaves in their operative position. The projector I is then "taken from its position upon the bottom wall I4 as shown in Fig. 4 and is rested upon the top face of the top wall |3 as illustrated by the dot "and dash lines in Fig. 6. The films H are then removed from their auxiliary shelf l9 and placed in the projector H and the electric lead cord thereof is plugged into a conventional house outlet for supplying the needed current to run the projector II. To again collapse the stand to the position shown in Fig. 1, the above procedure is reversed.

According to the'modification of the invention shown in'Figs. 13 to 16, the construction of the combined carrier and stand is similar to that previously: described except for the provision of a novel means for retaining the U-shaped brackets 3|] of the lugs to which the carrying handle 29 is attached in an operative or inoperative position without requiring the complete removal of these U-shaped brackets 30' from the openings In this form of the invention the U-shaped brackets 30' are formed of tubular material and a plate is mounted within each of the arms of the bracket 30'. Each of these plates is provided with a pair of outwardly extending pins 4|. These pins 4| are arranged in a spaced superi imposed position upon each of the arms of the brackets 30. These pins 4| are projected through openings provided by one of the side walls of each of, the arms of the brackets. Between the pins 4| each of the plates 40 is provided with a stem 42 which extends through an opening formed in the said wall of the brackets between the pins 4|.

A leaf spring 43 is mounted upon the other side of the plate 40 and engages the inside face of the tubular material from which the brackets clips 29' of the carrying handle 29. vHowever,

when the spring clips 29 are removed from the brackets 30" of the lugs, it is possible to press the plate inwards by pressing the stem 42 to cause the bottommost pins to be withdrawn from the openings 44.

The brackets 30' may now be dropped to a lowered position to permit the topmost pins 4| to be engaged with the openings 44 to retain the brackets 30' in an inoperative position with the intermediate arms thereof flush with the top face of the top wall I3. In other respects this form of the invention is similar to that previously described and like reference numerals are used for identifying like parts in each of the several views.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
